Objects

Objects refers to the various entities that can be defined within the file. They can include groups and attributes associated with the objects. Objects are organized in a hierarchical structure, allowing for efficient storage and retrieval of complex data, such as setup parameters and acquisition-related information.

All .nde files regardless of their technology are constructed with the following basic objects :

• acquisitionUnits
• probes
• wedges
• motionDevices
• dataEncodings
• specimens
• groups

Note that :

• All objects have an ‘id’ attribute
• In the .json file objects are expressed with a 's' and put in a list (even if there's only one object)
  • In the JSON file list items are in []
• Reference to other objects are made by expressing the name of the object (without the 's') + 'Id'
  • For example a reference to an object in the probes list would be 'probeId'
• Other objects than the basic objects exist within the file. These objects are included in some specific base object. For example, 'mountingLocation' is an object found in 'wedge' object.
• Object can be either specialized or basic. For example 'phasedArrayLinear' is a specialization of a 'probe' object. Specialized objects retain all the attributes of the source object but add new attributes under the specialization level.

Example of probe object with basic and specialization attributes.
